Wavetables, such as wavetable 342, are commonly used in audio processing. Thus, in the exemplary embodiment, a number of DMA channels are dedicated to wavetable operations. Queue list 401 may be dedicated to conventional DMA channels while queue list 402 may be dedicated to wavetable DMA channels. Correspondingly, a number of sub-buffer tables 380, previously discussed, may be dedicated to wavetable DMA channels without significant alteration from the sub-buffer tables disclosed. Further, some of FIFOs 306 may be dedicated to wavetable DMA channels.

The wavetable daughter board is a completely separate Synthesizer which takes MIDI IN/OUT from the external MIDI port and puts out audio to the video input of the AC97 CODEC. The only control our drivers have over it is volume
